   4 Subject: [PATCH] rtl8xxxu: Fix rtl8723bu driver reload issue
   5
   6 The generic disable_rf() function clears bits 22 and 23 in
   7 REG_RX_WAIT_CCA, however we did not re-enable them again in
   8 rtl8723b_enable_rf()
   9
  10 This resolves the problem for me with 8723bu devices not working again
  11 after reloading the driver.
